5 Claims. (Cl. 222-103) This invention relates to a paste filledcartridge and complementary dispenser adjustable to dispense paste fromthe cartridge.

Paste-like commodities such as tooth paste, shaving cream and the likeare particularly difficult to dispense conveniently. Such pastes areoften too heavy to flow easily from a rigid container and in additionusually exhibit a tendency to solidify or cake unless kept in anairtight container. conventionally, such pastes are packaged in tubesmade of a pliable metal and squeezed by hand to meter a desired quantityof paste as determined by the user.

A principal object of the invention is to provide a paste dispenserwhich may be conveniently mounted on a wall surface such as in abathroom and arranged with an adjustable screw which causes pressure tobe exerted against a pliable paste filled cartridge so that paste isdispensed from the cartridge upon adjustment of the screw, the devicebeing so arranged that upon the paste being expended a new fullcartridge may be installed conveniently without need of special tools orequipment.

Another object of the invention is to provide a paste dispenser with afixed plate and sleeve arrangement with a paste filled collapsiblecartridge disposed between a head plate of the sleeve and the fixedplate with a mechanism for forcing the sleeve head plate against thefixed plate to compress the cartridge and force a quantity of paste froman orifice of the cartridge.

A further object of the invention is to provide an improved dispenseremploying an oval-shaped collapsible cartridge filled with paste andapertured through the center to receive a member engaged with plates ontwo sides of the cartridge.

Another object of this invention is to provide a novel paste dispenserwhich mechanically meters a desired quantity of paste from a cartridgeto a brush employed by the user so that more accurate control ofquantity of charge is obtained than heretofore.

A feature and advantage of the invention is its attractive adjunct tothe usual bathroom fixtures so that it may, if desired, be employed as amedium of advertising for paste products or the like.

Another feature and advantage of the invention is its simplicity ofinstallation, refill and capacity to take up a minimal space.

A still further feature and advantage of the invention is itsself-sealing dispensing spout which eliminates troublesome screw-on capsconventionally used with paste containers.

Other objects of the present invention will become apparent upon readingthe following specification and referring to the accompanying drawingsin which similar characters of reference represent corresponding partsin each of the several views.

In the drawings:

Fig. 1 is a perspective view of the invention shown mounted on a wallsurface with a portion cut away to show interior structure.

Fig. 2 is a sectional view of Fig. 1 taken along lines 22;

Fig. 4 is a perspective view of a collapsible cartridge for use with thedispenser of Fig. l.

The preferred embodiment of the invention comprises a fixed oval plate12 with a complementary shaped cylinder 14 slidably mounted on theplate. One end of cylinder 14 is capped by a head plate 16 forming a'compression chamber 17 interiorly of the cylinder Wall between fixedplate 12 and head plate 16. Fixed plate 12 is rigidly mounted on abracket 18 by an arm 20 projecting laterally from the bracket to suspendthe fixed plate in spaced parallel alignment with bracket 18. Arm 20 iscentrally apertured along its central longitudinal axis as at 22 andthere threaded to receive a screw 24. Screw 24 is slidably engaged withaperture 26 formed centrally in head plate 16 and passes through thecenter of com pression chamber 17 and an aperture 28 formed centrally inplate 12 to engage the threads of aperture 22. The head of screw 24 isflanged at 31 to frictionally engage with head plate 16. Flange 31 isformed with a finger grip 32 projecting laterally from flange 31 whichmay be used to turn screw 24 and to force head plate 16 against thefixed plate 12.

A paste filled oval cartridge 35 for the dispenser is formed of pliablematerial such as pliable plastic. The cartridge 35 is generally eggshaped and dimensioned to fit within compression chamber 17. An aperture37 is formed through the center of the cartridge 35 disposed to alignwith apertures 26 and 28 so screw 24 can pass through the cartridge toengage threads 22.

In operation bracket 18 is fastened on a vertical wall surface 33 suchas a bathroom wall by screws 34. Cartridge 35 is disposed in compressionchamber 17 with screw 24 in communication with arm 20 through cartridgecenter aperture 37. Cartridge 35 is provided with a centrally disposeddownwardly depending spout 38 orificed at its tip, as at 39, to form asingular opening to the interior paste filled cavity of the cartridge.Cylinder 14 is provided on the bottom portion of its wall with anelongated notch 41 to receive the spout 38. When the cartridge isinstalled as shown in Figs. 1 and 2, spout 38 depends downwardly fromthe bottom of cylinder 14 through notch 41. Orifice 33 is of theself-sealing type wherein paste Within the cartridge 35 is allowed topass through the orifice only under pressure.

When screw 24 is turned, head plate 16 is forced against fixed plate 12.This forces paste in cartridge 35 out of orifice 39 so that it may bedeposited on an article such as a tooth brush 42. The screw typeattachment facilitated by screw 24 provides a micrometer adjustmentwhich allows close control of the quantity of paste metered fromcartridge 35.

After the contents of cartridge 35 have been exhausted screw 24 isremoved and cylinder 14 is withdrawn so that the expended cartridge maybe discarded. A new paste filled cartridge 35 is placed inside cylinder14 with its aperture 37 in alignment with aperture 26, screw 24 is theninserted through apertures 26, 28 and 37 and screwed into the threads ofaperture 22 wherein the device is again ready for use.

The bottom of bracket 18 is bent to form an outwardly projecting flange46 notched as at 47 to receive conveniently and support tooth brushes42.

Although the foregoing invention has been described in some detail byway of illustration and example for purposes of clarity ofunderstanding, it is understood that certain changes and modificationsmay be practiced within the spirit of the invention as limited only bythe scope of the appended claims.

What I claim is:

l. A paste dispenser comprising a collapsible cartridge formed with anaperture through the center of the cartridge, said cartridge having acavity adapted to carry paste and an orifice opening to the cavity, afixed plate, a sleeve mounted slidably over said fixed plate, a secondplate covering one end of said sleeve, said cartridge being removablypositioned interiorly of the wall of said sleeve between said firstplate and second plate, adjustable means passing through the aperture ofsaid cartridge operable to move said plates relative to one anotherwhereby the cartridge is compressed and the contents thereof forcedthrough the orifice of the car- .tridge.

2. A paste dispenser comprising a first plate, a sleeve mounted slidablyover said plate, means comprising said first plate and sleeve to preventrelative rotational movement between said sleeve and said plate, asecond plate covering one end of said sleeve, a collapsible cartridgeadapted to carry paste positoned interiorly of the Walls of said sleevebetween said plates, adjustable actuating means to move one platerelative to the other plate, said cartridge formed with an aperturethrough which said adjustable means is positioned, said cartridge havingan orifice to meter paste from said cartridge upon compression betweensaid plates whereby upon adjustment of said actuating means saidcartridge is compressed between said plates to meter paste therefrom.

3. A paste dispenser according to claim 2 and wherein said first plateand sleeve are formed in the shape of complementary ellipses.
